Re: [xsl] recursive sorting by element name -> Xalan Issue

["Davis Ford" <davisford@xxxxxxxxx>]

Hi Michael, thanks for clearing that up.  I am *almost* there now,
with the current incarnation of the stylesheet (below).

The only remaining issue I have appears to be with Xalan.  When I
serialize out a collection with JAXB, and apply the stylesheet (using
code posted previously), it sorts everything and I have no missing
attributes, except the DictionaryModelDescriptor node is now at the
bottom of the file instead of the top.  When I run with xsltproc on
mac/linux it places it at the top.

Any idea why I get this behavior?

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
    xmlns:xalan="http://xml.apache.org/xslt"; >

    <!-- The xalan param gets back indentation that seems to be broken
in the java api  -->
    <xsl:output method="xml" indent="yes" encoding="UTF-8"
xalan:indent-amount="4"/>
    <xsl:strip-space elements="*" />

    	<xsl:template match="/">
		<xsl:apply-templates />
	</xsl:template>

	<xsl:template match="@*|node()">
  		<xsl:copy>
			<xsl:copy-of select="@*"/>
			<!-- copy all attributes before applying templates to children only -->
			<xsl:apply-templates select="node()">
				<xsl:sort select="- boolean(self::DictionaryModelDescriptor)"/>
				<xsl:sort select="@typeName"/>
      				<xsl:sort select="name(.)"/>
      				<xsl:sort />
    			</xsl:apply-templates>
  		</xsl:copy>
	</xsl:template>

</xsl:stylesheet>
